Abstract: An apparatus for communication with a plurality of devices using time divisional multiple access (TDMA) is described. The apparatus includes processing circuitry configured to for a particular duration, scan a first channel for one or more data packets being transmitted over the first channel to determine if the apparatus is experiencing signal interference. In response to determining that the apparatus is not experiencing signal interference, the processing circuitry is configured to output a first beacon at a first time using TDMA, wherein the first time is a predefined interval amount of time after an output time of a most recent beacon previously output by the apparatus. Otherwise, the processing circuitry is configured to output the first beacon at a second time using TDMA, wherein the second time comprises the first time plus-or-minus a time shift period.

Abstract: An apparatus includes processing circuitry configured to output a first superframe configured in an initial superframe mode that allocates each slot of a plurality of slots for wireless communication to a first protocol at a first frequency band, a second protocol at the first frequency band, or a third protocol at the first frequency band. The processing circuitry is also configured to output a second superframe configured in a multi-frequency superframe mode that allocates: i) at least one slot of a plurality of slots for wireless communication to the first protocol, the second protocol, or the third protocol at the first frequency band, and ii) at least one slot of the plurality of slots for wireless communication to the first protocol, the second protocol, or the third protocol at the second frequency band.
